Processes of sharing and separating, power plays, negotiations, and refusals are not merely depicted in music—in polyphony, they actually take place. This makes polyphony an important component of artistic intervention in social space. During its first funding period (2022-2026), the musicological project "Polyphony as Experimental Sociality" examined polyphonic interventions in the field of contemporary music. The research demonstrated that polyphony is neither apolitical craft nor the product of pre- existing structures: rather, through its respective systems of rules, it constitutes a network of social dynamics from which structural participation in sound emerges. Informed by decolonial critique, the research further showed how polyphony is able to intervene in sound and public spheres in politically and socially situated ways.
